Title (EN) MULTI LAYER VEHICLE TRACKING SYSTEM
(FR) SYSTEME A NIVEAUX MULTIPLES DE POURSUITE DE VEHICULE
Abstract:
(EN) A vehicle tracking system is disclosed. The system uses management data generated or stored within a GSM digital mobile telephone to enable the location of the telephone to be determined by triangulation. The management data used includes Base Station Identity Code, Base Station Frequency, Signal Strength, Signal Quality and Timing Advance. The tracking system can also be used to track or locate shipping containers or to track or locate an individual carrying the mobile telephone.
(FR) L'invention concerne un système de poursuite de véhicule. Ce système met en application des données de gestion générées ou mémorisées à l'intérieur d'un téléphone mobile numérique GSM, afin de pouvoir déterminer l'emplacement du téléphone par triangulation. Ces données de gestion utilisées comprennent le code d'identité de la station de base, la fréquence de station de base, la force du signal, la qualité du signal et l'avance de synchronisation. On peut également utiliser ce système de poursuite afin de rechercher ou de localiser des conteneurs de fret ou un individu portant le téléphone mobile.
